Night guards, also known as occlusal splints or dental splints, are dental devices used to protect the teeth and alleviate the symptoms of bruxism, a condition characterized by teeth grinding and clenching during sleep. These custom-made appliances are designed to fit comfortably over the teeth, providing a cushioning effect that helps prevent the upper and lower teeth from coming into contact with each other. By creating a barrier between the teeth, night guards absorb the forces generated during grinding or clenching, reducing the potential damage to tooth surfaces, jaw joints, and surrounding muscles. Additionally, night guards can help alleviate the associated symptoms of bruxism, such as jaw pain, headaches, and facial muscle tension. They also assist in maintaining the proper alignment of the jaw and promoting a more relaxed and comfortable sleep. Night guards are typically recommended and fitted by dental professionals, ensuring a precise fit that is specific to the individual's dental structure and needs. Regular use of a night guard can effectively protect the teeth from the harmful effects of bruxism and contribute to overall oral health and well-being.
